To integrate BlendVision One DRM, add related options to source options as shown below.

drmUrl can be found on here, and playbackToken is the same token to start a playback session.

if let licenseString = "https://drm.platform-qa.kkstream.io/api/v3/drm/license",
   let fairplayCertString = "https://drm.platform-qa.kkstream.io/api/v3/drm/license/fairplay_cert",
   let licenseUrl = URL(string: licenseString),
   let certUrl = URL(string: fairplayCertString) {

   // Create drm configuration
   let fpsConfig = UniFairPlayConfig(licenseUrl: licenseUrl, certificateUrl: certUrl)
   
   // Example of how message request data can be prepared if custom modifications are needed
   fpsConfig.prepareMessage = { spcData, assetId in
      spcData
   }

   // Example of how certificate data can be prepared if custom modifications are needed
   fpsConfig.prepareCertificate = { (data: Data) -> Data in
      // Do something with the loaded certificate
      return data
   }
   
   fpsConfig.certificateRequestHeaders = "certificate header"
   fpsConfig.licenseRequestHeaders = "license header"
   sourceConfig.drmConfig = fpsConfig
}
